1. A method of printing a three-dimensional object, the method comprising:
providing a printing system which extrudes a filament material to form a printed three-dimensional object, the printing system having a computing device for controlling the printing system and a nozzle for extruding the filament material from the printing system;
calculating a first amount of filament material to be extruded from the nozzle with the computing device;
extruding the first amount of filament material from the nozzle at a starting position of the printed three-dimensional object;
ceasing the extrusion of filament material from the nozzle when a first extruded amount of filament material is deposited at the starting position;
calculating a movement path of the nozzle with the computing device;
moving the nozzle along the calculated movement path to draw the first extruded amount of filament material along the movement path, wherein the nozzle contacts the first extruded amount of filament material to pull by the first extruded amount of filament material along the calculated movement path, and wherein the nozzle does not extrude the filament material when drawing the first extruded amount of filament material along the calculated movement path;
calculating an end point of the printed three-dimensional object with the computing device; and
extruding a second amount of filament material from the nozzle at the end point to anchor the first extruded amount of filament material drawn by the nozzle at the end point.
